IMPROVEMENT IN PASSENGER ENUMERATORS AND CLASS IFIERS.

Specification forming part of Letters Patent No March To all whom it mayconcern:

Be it known that I. EDWIN CHESTERMAN, of No. 50 North Fifth street,Philadelphia, Pennsylvania, have invented an Improved PassengerEnumerator and Classifier, of which the following is a specification:

The object of my invention is to construct an instrument which shallrecord and classify the amounts received as fares from passengers.

It consists in the arrangement of two or more counting-registers in onecase, which is so secured that no person can by any possibility set backor tamper with the registering apparatus. Each eountingregister isactuated by its own separate pin projecting through to the outside ofthe case. A button orknob is placed on the outside end of this pin,which the carconductor presses to record the character of the farereceived. The proper button to press is indicated by such words as cash,ticket, exchange, half-fare, printed on the case, in close proximity tothe button, so that the passen ger himself can see ifthe proper buttonis struck.

The bell is struck by an independent mechanism of its own, which is soconnected with the separate push-knobs that the pressing of any one ofthe buttons will ring the bell or gong within the case, but only actuateits own particular register. The box inclosing the mechanism is closedby a lid riveted on, or otherwise so securely sealed that it cannot beremoved without damaging the case and showing that the attempt has beenmade. The box cannot be opened, and if the mechanism gets out of orderit must be sent to the manufacturer for repairs. In this lid is a plateof glass over the counting-registers, through which they can be read bythe receiver and the amount entered in a book at the end of every trip.The register works continuously without setting, and bysubtraeting thefigures at any given trip from the amount recorded at the nextsucceeding one, the number of fares received is ascertained. The glassplate is covered by a locked lid, so that the conductor cannot examinethe state of the register. By this he is prevented from knowing thestate of the register, and if any attempt should be made to defraud bystriking the wrong knob, there is no possibility of 153,475, dated July28, 1674; application tiled 17, 1874.

the conductor harmonizing his account to correspond, as he is working inthe dark.

lteferring'to the drawings, Figure l is a plan of the machine, with theoutside lid removed. Fig. 2 is a side elevation of the machine. Fig. 3is a plan, showing the interior mechanism of the machine.

A is a shallow case or frame, to which the mechanism is secured. a is aspring-lock secured to the side of the case. 0 D E H are four similarsets of counting-registers, each wheel having on it the ten. figures anda tap pet, c. K is a knob secured upon the rod k. This rod passesthrough a hollow box, k, and connects with the slide M. The slide M isguided in its motion by the screw m at one end, and the rod k, workingin the box 76, at the other end. A spring in the box k keeps the knob Kextended. The pawl n is hinged upon the slide M and is kept in contactwith the first registering-wheel by the spring n. P is a sliding bar,moving in guides 19. R is the bell-hammer, pivoted at 0*. It is kept incontact with a stop,4" by the spring 1*. A pin, 1, projects from thelower arm of the bellhammer. p is a pawl, kept in contact with a stop bythe spring 19 S is the gong or bell. The sliding bar P is raised so thatit can pass over the pawl 12. The lug m making part of the slide M,projects upward, so that the pin m will come in contact with thecross-bar P when the knob K is pushed inward. These relative positionsare best seen in sectional elevation, Fig. 4. T is the lid, having lugsat one end, which pass under corresponding lugs t in the case A, and theother end is secured by the rivet 12 A screw may be used in place of therivet, in which case the head is sealed by a wax or metal seal. I preferto solder the lid down, thus preventing any possibility of the mechanismbeing tampered with, either by the conductor or receiver, and yet permitthe register to be read through the transparent plat-e W when the outerlid is unlocked. \V is a transparent plate through which the registerscan be read at any time. X is an extra cover or lid, hinged to the lidT, and covering the glass plate, to prevent the conductor seeing thestate of the registers. ,This lid is fastened by the spring-lock a.Before using the machine, the lid X is unlocked and the receiving-clerknotes down the state of the registers U 1) E H and looks the lid. Wewill now suppose the knob K, operating upon the counting-registerO,placed under the Word cash to bepressed. The slideM, moving forward,will cause the register 0 to count one. The stop m will also pressforward the slide P and force the pawl 72 against the stop r raising thehammer until the pawl slips past the stop 2' and the hammer strikes thebell every time one additional fareis recorded. On releasingthcthuuibfrom the knob K, thepawlp slips past the pin 1 in consequence of the barP returning to its first position by the pressure of the spring 1). Asthe bar P is only kept in contact with the pins m by the pressure of thespring 1%, the pressing of any particular knob K of the register 0 willstrike the bell, but have no effect upon the other registers, D hen thelid X is again opened, the

number of each class of fares received is easily computed.

I make no claim to the particular counting registers herein shown, nordo I confine my self to the number of Wheels used.

I elain1 l. The combination of two or more countii'ig-registers, G D EH, in one case, with an alarm-bell, S, and a single intermediatestriking mechanism operated by the several pushknohs, K, substantiallyas herein described.

2. The arrangement of one or more continuously-countin g registers, in anon-op enin g case, permanently riveted or fastened so that accesscannot be obtained to the interior mech anism, the said case having atransparent plate, W, as herein set forth.
